Recording mixes with 2xCDJ 900NXS & A&H xone92 - help

Hi, 

i am wanting to record mixes via Rekordbox. My set up consists of 2 CDJ 900NXS & Allen & Heath Xone:92 mixer. i can connect my CDJs to my laptop (Macbook pro) but when i select a track it doesnt show on my CDJs, is this because i only have the free version of Rekordbox and will i need to purchase the full Rekorbox DJ version to do so? also does anyone know how to connect a Xone:92 to a laptop and rekordbox? 

cheers.
